Once a big horse and a small donkey were traveling together, carrying all kinds of  things on their backs for their owner. The big horse was very strong but  he carried as heavy as the small donkey.
The donkey was able to keep up with the big horse in the b         . But after a w       , the donkey began to feel too tired  to keep up any more. So the donkey asked the horse, “Brother Horse, could you please help me? I am a           I  can’t go on carrying as heavy as you can.”
“No, you carry yours. I carry mine. It is not my p          that you are not as big and strong as me,” answered the horse, feeling very  p           that he was stronger.
Not long after that, the donkey finally f        down to the ground and died.
Their owner m           what the donkey carried  onto the back of the horse. Having to  carry the double load(负荷物) for the r          of the journey, the horse now knew he should have h          the donkey out. That way at l           the donkey could carry something. The horse was sorry for being too selfish, but it was too late.
